The invention relates to an apparatus (10, 110) for the conveying of viscous material from a drum-like container (12), which has a container bottom (14) and a circumferential container wall (18) extending from the container bottom (14) to an upper rim (16) of the container, which is open at the upper rim (16) of the container, the apparatus having, for closing of the container (12), a follower plate (26) having a material outlet (28) attached to a conveyor pump (30), wherein the follower plate (26) can be moved up and down in the container (12) while being in sealing contact against an inside face of the container wall (18) turned toward it, and having a lifting device (22) for raising and lowering of the follower plate (26), wherein the lifting device (22) has a drive unit. According to the invention, a protective device (32, 132) having a protective member (34, 134) is provided, which is disposed in such a way with respect to the follower plate (26) and the container (12) that, upon introduction of the follower plate (26) into the container (12), it annularly surrounds on the one hand the follower plate (26) and on the other hand the container (12) in the region of the upper rim (16) of the container. The protective device (32, 132) additionally has at least one switch (52, 152, 154) for switching-off of the drive unit upon an at least partial exposure of the upper rim (16) of the container by the protective member (34, 134) during the introduction of the follower plate (26) into the container (12).

A fluid transfer apparatus for transferring fluid from a bulk storage container to a secondary container, such as from a pail to a cartridge. The apparatus may include a vertical press and a modular follower plate. The modular follower plate may be affixed to the vertical press such that the vertical press can be operated to force the modular follower plate progressively farther down into the bulk storage container. The modular follower plate may include a secondary container seat upon which a secondary container is fitted for filling. The modular follower plate may include a through-hole that allows fluid disposed below the modular follower plate to be forced upwardly into the secondary container as the modular follower plate is press downwardly into the fluid with the bulk storage container. The modular follower plate may include a circumferential seal that engages the inner surface of the bulk storage container.

The invention relates to an apparatus (10) for the conveying of viscous material from a drum-like container (12), which has a container bottom (14) and a circumferential container wall (18), extending from the container bottom (14) to a container upper side (16) and is open at the container upper side (16), with, for closing of the container (12), a follower plate (20) having a material outlet (26) attached to a conveyor pump (40), wherein the follower plate (20) is provided with an annularly circumferential wiper ring (28), wherein the wiper ring (28) has a radially outwardly extending contacting part (34) for contact against an inside face (36), turned toward the follower plate (20), of the container wall (18), and wherein the contacting part (34) can be pressurized with a variable pressing force for pressing against the inside face (36) of the container wall (18). According to the invention, it is provided that the follower plate (20) is mounted by means of at least one vertically extending retaining rod (58) on a horizontally extending crosspiece (52), which is mounted on or close to a first end (54) on a lifting device (50) for raising and lowering of the crosspiece (52), while its second end (56) is free.

A method for conveying viscous material out of a barrel-like container open towards the top and having a bottom and a circumferential wall extending from bottom to top, uses a device having a follower plate for closing the container. The plate has a circumferential wiper ring having a radially outwardly protruding contact portion for contacting an inner container wall face facing the plate. A variable pressing force can be applied to press the contact portion against the inner face. The plate, following a decreasing material level and resting on the material surface, is moved bottomward, and, after the container is emptied, is moved away from the bottom, and the contact portion is pressed sealingly against the inner face while the plate moves bottomward. The sealing effect between the wiper ring and the container wall is suspended during plate movement away from the bottom by reducing the pressing force.
